Description

  The present invention relates to a track approach warning system used at a railway station.

  Railway vehicles are driven between stations as trains. There is a platform for passengers to get on and off at the station. Since the platform is close to the track, if a person on the platform gets too close to the track, there is a risk of falling from the platform or contacting a moving vehicle.

  2. Description of the Related Art Conventionally, there has been known a monitoring device that performs image processing on images from a camera that captures images in a track and on a platform and predicts the fall of people and objects from the platform (see Patent Document 1). However, since this monitoring device stops input of an image captured by the camera when it is determined that the train is approaching (see FIG. 2 of Patent Document 1), it cannot prevent a person from coming into contact with the approaching train. .

  There has been proposed a fall prevention system that performs image processing on an image from a CCD camera and prevents falls from a person's home or contact with a train (see Patent Document 2). This fall prevention system has a CCD camera provided on the roof of the platform, and detects trains and people on the platform. However, this fall prevention system does not detect a person who falls from the home. In this fall prevention system, the CCD camera is a very important part because it detects a person, and maintenance such as inspection and lens cleaning is indispensable. The CCD camera provided on the roof requires high place work (work done in a place with a height of 2 m or more) for maintenance, and is not easy to maintain.

  A safety monitoring device that images a home end with a stereo camera has been proposed (see Patent Document 3). However, in this safety monitoring device, since a plurality of stereo cameras are installed downward at a position higher than the human head (see FIG. 1 of Patent Document 3), work at a high place is required for maintenance, and maintenance is not easy. Absent.

Since the home is long, a plurality of housings 2 provided with the human detection sensors 3 are usually used. Considering the positions of the doors of all vehicle types that stop at the station and the allowable deviation of the stop position, the installable position of the housing 2 at the station is determined. Since the housing 2 does not perform a mechanical operation, it can be made thinner than the movable home fence or the fall prevention inhibiting movable protective fence, and a passage width on the platform P can be secured large.

  The human detection sensor 3 is also called a “customer detection sensor”. In the first embodiment, the human detection sensor 3 has a two-dimensional TOF sensor. The two-dimensional TOF sensor scans a laser beam on a plane (circumferential shape), measures the distance to the object, and detects an object having a predetermined size or more on the plane. The light emitted from the two-dimensional TOF sensor is an infrared laser beam. The distance is measured by an optical time-of-flight ranging method based on a time of flight (TOF). The human detection sensor 3 compares the data measured by the two-dimensional TOF sensor with the data when no person is present, detects an object, etc., calculates the position of the detected object from the light emission direction and the measured distance, Whether or not the detected object is a person is determined from the size of the detected object. The human detection sensor 3 has a detection range set in advance, and detects a person existing in each detection range.

Note that a video camera may be used instead of the two-dimensional TOF sensor. When another system (for example, a vehicle stop detection system) capable of detecting the stop of the vehicle on the line is provided at the station, the input connected to the system is used as the stop of line detection unit 42 instead of having a two-dimensional TOF sensor. It may have an interface or the like.

  In the present embodiment, the departure detection unit 43 shares the two-dimensional TOF sensor with the standing line stop detection unit 42. Note that a video camera may be used instead of the two-dimensional TOF sensor. When another system (for example, a vehicle stop detection system) capable of detecting the departure of the vehicle is provided at the station, the departure detection unit 43 may include an input interface connected to the system. Further, as the departure detection unit 43, an input device (push button) operated by the conductor when the vehicle departs may be provided in the housing 2 or the like.

The audio output by the speaker 52 of the notification unit 5 is preset in the control device 7 in accordance with each of the case where the vehicle is not detected, the case where the vehicle is detected, and the case where the vehicle is detected. ing.

  When the human detection sensor 3 detects a person in the second on-home detection range D2 and the vehicle detection unit 4 does not detect the stop of the vehicle on-line, the person is at home It is in a state of approaching the edge. For this reason, the sound output by the speaker 52 is set to a content that makes the danger recognized more than when a person is detected in the first on-home detection range D1.

  The trajectory approach warning system 1 is configured such that when a person is detected in the second on-home detection range D2 by the human detection sensor 3 and any of vehicle entry, stoppage, and departure is detected by the vehicle detection unit 4, The control device 7 displays a warning on the conductor warning display lamp 8.

  When the person detection sensor 3 detects a person in the on-orbit detection range D3 and the vehicle detection unit 4 does not detect the on-line stop of the vehicle, the control device 7 displays a driver notification display. A notification is displayed on the lamp 6. This is a state in which a person falls from the platform and is on the track, and the driver who has recognized the notification by the driver notification indicator lamp 6 applies an emergency brake to stop the vehicle.

  As described above, according to the trajectory approach warning system 1 according to the present embodiment, the person detection sensor 3 detects a person existing in the on-home detection range Dp (D1, D2), thereby notifying the person on the home of an alarm. Thus, it is possible to prevent the vehicle from falling from the home and coming into contact with the moving vehicle.
